There are tons posts of dynamat type products melting/failing in the texas heat. I think unless your trying to collect on your show car insurance you might want to reconsider mounting that above your turbo and intercooler.

Bingo. Not sure though if the actual "blanket/liner" melts or the clips melt allowing the liner/blanket to drop over the fire (althoug the liner is already in close proximity lol).

I believe also the material of the underhood liner acted as a thermal barrier/insulator to help prevent heat transfer to the hood = damage to your paint.

If you want a proper hood liner, order the material online and cut what you need and make it fit.

If you're going for show, I'd just repaint/clean up the paint on the underside of the hood, and make sure you have your heatshield on your manifold (at a mininum).

I plan to just have all my "hot parts" titanium coated or some sort. It's amazing how much ambient heat is decreased from this.

Honestly, I never thought of underhood liners originally to be much protection for paint with proper heat shields, etc, but more a fire blanket/sound reduction. One thing to remember, a lot of the older cars (such as ours) have aged (general wear and tear) enduring multiple weather conditions, and the paint chemistry was a bit different back then perhaps. I'm not bringing this up to state that protecting the paint is a moot point, though (just adding rationalization to a side). But I will agree that these liners may confer some protection for the paint from the heat, being secondary to why liners are now used.
